PORTABLE HEATER.

Application filed December 23, 1908.

Specification of Letters Patent.

Patented May 31, 1910. Serial No. 468,956.

To all whom it may concern:

Be it known that I, SAMUEL BERGSTEIN, a citizen of the United States,and a resident of Youngstown, in the county of Mahoning and State ofOhio, have invented a new and Improved Portable Heater, of which thefollowing is a full, clear, and exact description.

This invention relates to portable heaters, and particularly to a heaterwhich consists of a hollow body adapted to contain an absorbent materialsuch as asbestos or the like, and provided with openings on either sidethereof, at which a liquid fuel, such for example, as alcohol, held inthe absorbent material can be ignited, and lids movably secured to oneof the ends of the body and adapted to t over the sides thereof.

The object of the invention is to provide a device of the classdescribed, simple and serviceable in construction and inexpensive tomanufacture, which is of a convenient size to be carried in the pocketof the user, and which is provided with two lids, the latter incombination with the body forming a stand on which an object to beheated can be positioned.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective vlew of an embodiment of my invention; Fig. 9.is a cross section on the line 2--2 of Fig. 1; Fig. 3 is a longitudinalsection on the line 3 3 of F 1g. 2; and Fig. 4 is a longitudinal sectionof a modified form of my device.

Before proceeding with a more detailed description of my invention, itshould be understood that I provide a portable heater which, as beforedescribed, consists of a hollow body adapted to contain a liquid fueland provided with openings at which the fuel can be ignited, and lidssecured to the body and adapted to fit over the sides thereof to closethe openings. lVhen the device is open for use, the lids in combinationwith the top of the body, form a stand on which any object to be heatedcan be placed. The openings in the body are located at a point slightlybelow the top, so that the necessity of having brackets for supportingthe object is entirely obviated. In the closed position, the alcohol isprevented from evaporating, as the lids form tight closures for the bodyopenings. If desired, one side may be opened and the other left closed,thereby reducing the amount of heat. The interior of the body may befilled with any suitable absorbent material, such as asbestos, or acombination of asbestos and sandstone.

In the specific form shown in the drawings, I provide a hollow body 1,formed of any suitable metal and preferably rectangular in shape.Located on each side of the body and slightly below the top thereof is aplurality of openings 2. Arranged within the body is a suitableabsorbent material 3, such as asbestos or the like, which serves toregulate the burning of any suitable liquid fuel that may be used withthe device. Mounted at the rear of the body are hinge brackets 1 havingtheir opposite ends 5 formed to constitute sleeves. I further providelids 6 having rims 8. The back 9 of each lid is provided with extensions10 bent to form sleeves. The lids are adapted to be pivotally arrangedat the back of the body, so that the sleeves will register with thesleeves 5 of the body, so that hinge pins 11 may be passed through theregistering openings to secure the lids movably in position.

In the modied form shown in Fig. 4t, I have provided a hollow body 12,preferably rectangular in form, having lids 13 pivotally arranged on theback thereof and adapted in the closed position to fit over the sides.The body is provided with a plurality of openings 14. The body has itsinterior divided by means of a partition 15, the latter beingprovidedwith openings 16, through which wicks 17 extend. The upper portion ofthe body 12 receives any suitable absorbent material 18, such asasbestos or the like, while the lower portion acts as a reservoir tocontain a liquid fuel 19, such as alcohol or the like, the wicks 17serving to conduct the fuel to the absorbent material from thereservoir.

In operating the device, the lids are opened,so that they present asupport on which an object can be placed, and the liquid fuel is ignitedat the openings. In filling the device, one lid is closed and the liquidfuel is poured into the openings at the other side. The lids also, whenopen, brace the device at each side so that it can be positionedoperatively.

It should be further understood that I do not limit myself to the specicform shown in the drawings, as others equally advantageous may beemployed without departing from the spirit or the scope of theinvention.

Having thus described my invention, I claiin as new and desire to secureby Letters Patent:

l. A heater, comprising a hollow body, a partition within said body,whereby the lower portion of said body is formed to constitute areservoir adapted to receive a liquid fuel, an opening in saidpartition, a wick adapted to be arranged within said reservoir and toproject through the opening in said partition, an absorbent materiallocated in the upper portion of said body, openings in each side of saidbody at which the liquid fuel held by said absorbent inaterial can beignited, and lids movably secured to said body and adapted to close saidopenings, said lids further serving as a support for mounting an lob]ect to be heated.

2. A heater comprising a hollow body for containing a liquid fuel, saidbody having a fiat base whereby it may stand alone on the support and aclosed iiat top for receiving an object to be heated, and having sideopenings adjacent to the top for the emission of the products ofcombustion and lids hinged to the side edges of the hollow body forassisting in the support of the said body when open.

In testimony whereof I have signed lny naine to this specification inthe presence of two subscribing witnesses.

SAMUEL BERGSTEIN.
